Hey everyone,

So I don't have a clear picture in my head of our development cycle, and I don't think it's well documented. I didn't want thread jack, but in another thread Mike wrote:

My first question is, how are these two branches related, because I've been submitting things against master, and then switching it to be against 1.2.x when I was asked. From what I have gathered, 1.2.x is for bugfixes, and master is for new features.


That is correct.
 
Can someone clarify the current process, with a section like "Submitting new Pull Requests" -  this should probably go into one of these places:
http://matplotlib.org/devel/coding_guide.html
http://matplotlib.org/devel/gitwash/index.html


This is the essence of the gitwash process.  Perhaps it needs to be clearer.
 
My second question is that, if I do have the right idea about the current process, and the distinction between master and 1.2.x, should we change this? (I think we should).

The trouble is that it seems to me now for a bugfix, if it is submitted against 1.2.x, it won't be fixed in master until changes from 1.2.x are merged back into master. So now as a developer trying to follow "bleeding edge" matplotlib, I either have to live with bugs that have been fixed in 1.2.x if I want the features from master, or if I want the bug fixes and follow 1.2.x, I miss the new features in master.


A general rule is that whoever merges a bugfix to the maintenance branch should then also manually merge the maintenance branch down to master.
 
I think that the mental picture is sufficiently clearer if *everything* (bugfixes and new features) go into master, and then we backport the critical bugfixes against 1.2.x. This would be easier to do if the core developer merging the bugfix into master at least opens an issue for as a placeholder / reminder for the bugfix being a candidate to go into the maintenance branch. Because it seems like at this point, we aren't even sure if we're going to do a 1.2.1 release...


There are other git workflows, which are all perfectly valid.  If you can convince us to use another, feel free to propose one.  However, we have done a couple of releases with gitwash, and it has worked quite well for us given how small our maintenance overhead is.  Just have to remember to regularly merge the maintenance branch to master.  That's all.

Cheers!
